Hey, Saw you in the 300 club...Thought I needed to post a little something to you. First remember you are not alone, it may feel like that at times but you are part of a community.
Use the people in your life to draw strength, if not there, use this community to draw strength. You are part of a very special community, a community that is going through the exact same journey that you are going through. We all fail at times, sometimes it is harder for some to get back up. There is nothing that you are doing that someone in this community has not done before. The most important thing to remember is that there was a point in time where you looked at yourself and made a choice to change. When times are difficult like they are right now, think back to that time and what made you want to change and re-embrace that and draw strength from that and press on.
I have made some poor dietary decisions on my own journey but I learn from them and move on. Does that mean I will not make the same mistakes again? NO it most certainly will not but I know that if I can make the better choice the majority of the time I will get to where I need to be.
Stay strong.
(Sorry for being kinda preachy there)
